Survival Rates in Closed and Open Vitrification for Human Mature Oocyte Cryopreservation: A Meta-Analysis.

Background/aims: Survival of warmed oocytes is the first part and is one of the most important aspects of in vitro fertilization following oocyte cryopreservation. There is no definite conclusion about the difference in survival rates between closed and open vitrification for oocyte cryopreservation. This study aimed to investigate whether there is a difference in survival rates between closed and open vitrification for cryopreservation of human mature oocytes.

Closed versus open vitrification for human blastocyst cryopreservation: A meta-analysis.

Closed vitrification can minimize the risk of microbiological transmission through liquid nitrogen during the cooling, storage, and warming procedures. As cooling rates may reduce when closed vitrification is applied, clinical outcomes should be compared between closed and open vitrification in order to justify the use of closed vitrification. This study was conducted to investigate the differences in survival, implantation, clinical pregnancy, and live birth rates between closed and open vitrification for human blastocyst cryopreservation.

In vitro fertilization and embryo transfer outcomes in relation to myometrial thickness.

Purpose: To evaluate the effects of myometrial thickening on the outcomes of in vitro fertilization and embryo transfer (IVF-ET).

Methods: Four hundred thirteen patients, a total of 551 IVF-ET cycles, were divided into group A (<2.00 cm), group B (2.

A case of huge sclerosing stromal tumor of the ovary weighing 10 kg in a 71-year-old postmenopausal woman.

Sclerosing stromal tumor (SST) is a rare benign neoplasm of ovarian stromal origin and predominantly affects young women in the second and third decades. This tumor characteristically differentiates itself histologically and clinically from both thecomas and fibromas. We present a case of huge SST of the ovary weighing 10 kg in a 71-year-old postmenopausal woman with a brief review of the literature.
